They might as well hang the keys outside the door....not to mention they're stuck with a single CS, but the illusion of choice is there for the DIY compared to those evil professional installers.
There are plenty of mom and pop and a few nationals that would install a system within your cited budget and monitoring rate. There'd be a minimum contract and the equipment might be a lease. For that matter, there's guys out there that would support someone BYOD and pick up monitoring. Lynx and Simon kits can be had all day for the dollar amount you stated.
And in your case Ano, after digging through your exceptional wit, you're connecting a $1500+ panel on an install with multiple detectors cross zoned and abundant coverage with 3rd party integration to something that works "reliable and good enough" to save maybe $50-100 on the communications device because UL listing on the route is not important. It's just like you bought yourself a Ferrari and now are tossing on recapped tires because they're round, black and have a rough surface, but then expect close to the same performance.
The net result, for your particular judgement, is whether or not you wish the unit to be invisible to the CS, since you're going to be stuck dealing with dialer capture due to panel choice and whether or not your particular CS has a direct IP port via the third party cellular vendor or not, assuming you wish to increase the speed and performance of the dialer by eliminating the delay if the 3rd party vendor does DTMF panel emulation or how the particular CS takes data from the vendor to their receiver and how many accounts are involved....but hey, what do I know after 20 years in installing systems and building central stations.
